Polish officials forced Kaczynski plane to land

Mr Kaczynski died with 95 others when his presidential jet crashed on 10 April last year.

It was attempting to land in fog near the city of Smolensk in northwestern Russia.

The damning report lists Polish shortcomings leading to the crash and risks increasing tension between the two countries.

The Russian inquiry suggests that the plane was ordered to land as Mr Kaczynski would have been unhappy if it was diverted.

Tatyana Anodina, head of the Moscow-based aviation commission investigating the tragedy, confirmed that top Polish officials had been in the cockpit of the Tu-154 plane but also revealed they had pressured the crew.
